Default 2011 Sti P0172

Here is a list of all the modifications I have on the STI so far. Car was tuned by Jorge at IAG (Westminster, MD).

Accessport
Invidia catless downpipe
Invidia Q300 exhaust
AEM Cold Air Intake
Deatschwerks Top Feed 1000cc Fuel Injectors
Deatschwerks 65C fuel pump
Grimmspeed Electronic Boost Control Solenoid 3-port
Grimmspeed Air/Oil Separator
PERRIN Black Turbo Inlet Hose 3"
PERRIN parallel fuel rails
BLOUCH 20G-XT-R Full Ball Bearing Turbocharger 8cm outlet 3 inch inlet
IAG Performance Subaru External Wastegate Uppipe Kit with TiAL 44mm V-Band Wastegate & GTSpec GEN II style Header
IAG air pump delete
AMR TMIC
Older STI fuel pressure regulator swap


It seems the power band isn't very smooth and I get a P0172 whenever I go on a long drive. Anything over 80 miles I usually get the P0172 CEL. Sometimes it doesn't happen. It happens more consistently if I drive around in Intelligent Drive. I threw a P0244 recently while driving in Sport Sharp mode. That has only happened one time.

When I called IAG they said it might be one of my injectors stuck in the open position.

Anyone have any ideas on what I should do? New tune?

Thanks!

Anthony
